SPECIFICATION forming part of Letters Patent N0. 741,633, dated october 20, 1 S.

Application iiled November 16, 1901. Serial No.- 82,536. (No model.)

To all whom it may concern:

Be it known that I, JACKSON Gr. CROWDES, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Cableway-Carriage, of which the following is a full, clear, and exact description.

My invention relates to improvements in cableway-carriages, and particularly relates to means for picking up and discharging fallrope carriers. y

My invention comprises the novel features which will be hereinafter described, and particularly pointed out in the claims.

Figure 1 is a plan view of acarriage having my invention thereon. ,Fig. 2 is a side elevation of the same. Fig.' 3 is a side elevation of onel end of the carriage. Fig. 4 is a cross-sectional elevation of the carriage through the devicesV for holding the fall-rope carriers. Figs. 5 and6are'respectivelyasectional plan and elevation of one form of device increasing or decreasing the storageroom for the carriers by the reversal of the travel ofthe carriage. Fig. 7 is an end elevation of a carrier. Figs.l 8 and 9 are respectively a sectional plan and side elevation of a construction equivalent to thatshown in Figs. 5 and 6. Figs. 10 andll are respectively a side elevation and section of one end of a carriage embodyingl my invention and having a slightly-dierent'connection .from those shown in Figs. 1 and 2. Figs. A12 and 13 are sections of forms of friction devices used on wheel B.

One well-known manner of distributing and taking up the fallrope carriers employed upon cableways is to provide storage-space for the reception of the carriers upon one or both ends of the carriage and to vary the amount of this storage space or spaces by a device which is operated by the rotation of the carriage-supporting or trackway wheels, so as to push the carriers in succession from the rear end of the carriage and to provide room for their reception upon the advancing` end ofthe carriage.

My present invention is an improvement on the above construction in that it makes usev of the reversal of the carriage to cause an additional variation iu the storage-spaces for the carriers, adding a small amount to the storage-space at the receiving or forward end of the carriage and descreasing by a small amount the storage-space at the discharging or rear end of the carriage. The purpose of this is to insure ample room for the reception of the carriers when being picked up and to insure their prompt discharge from the discharge end of the carriage. lIn other words, the reversal of the carriage is relied upon to decrease the storage-space for the carriers at the end from which theyl would be discharged to the least permissible and yet retain the proper number of carri-ers thereon, so that their discharge will begin promptly as soon as the carriage starts 01T, while at the opposite end of the'carriage the storage-space is increased by the reversal of the carriage, so that there is ample room to receive and retain the carriers in place as they are reached.

In the drawings accompanying herewith embodiments of my invention are shown, which are in forms at present preferred by me, but which are not the only forms in which it may be embodied or the only forms now known to me.

Iwill first describe the form shown in Figs. 1 and 2. The frame A'has trackway or supporting wheels B, B', and B2 journaled therein and running upon ythe trackway-cable I, and wheels or sheaves R for thefall or hoist rope Q. The carriage-frame has parallel extensions u. a at each end, between which, upon suitable guides f"( see Fig. 4) extending lengthwise the carriage, are mounted to slide the members F F, which are the equivalent of the horn usually used to receive and hold the fall-rope carriers, which for convenience I will call the horn.V The two parts of the -horn are shown as each composed of an angle-iron having a raised portionfat its outer end to prevent the carriers being removed, except as they are pushed off, and a carrier-retaining spring member G, which are.' shown as flat bars supported from one end and extending above the horn or carrier-supporting members F and clamping-or-yieldingly holding the carriers between themselves and saidV one on each side at their upper ends and adapted to run upon the parts F of the horn.

Fig. 7 shows a carrier in which a block p', secured between the upper ends of the frame members, replaces the rollers.

The two angle-bars F are secured at one end to a cross-head E, which slides lengthwise the carriage in slots e in the side pieces ct a, which slots are, however, not solely relied upon to support and guide the cross-head. Journaled in suitable supports C upon the frame and held against end motion therein are threaded rods or shafts D D, which pass through threaded holes in the cross-head E. The axle of supporting-wheel B is connected with the threaded rods or shafts D by means of bevel-gears b d, sovthat as the carriage travels along the trackway the shafts D D are turned in the cross-head, and this crosshead, with the horn which is connected thereto, is shifted lengthwise the carriage, the position of the horn in its path of travel corresponding proportionally with the position of the carriage along the cableway. The pusher H, which engages the innermost carrier, and together with the horn F by their relative positions determines the number of carriers which may be held, is also mounted so that it may have a limited reciprocation lengthwisethe carriage. This pusher is shown as havingr slots 7L, through which pass bolts or pins h on the sides d a.

The supporting or trackway wheel B is provided with means by which the reversal of its rotation will shift the pusher in one direction or another. One means, which is shown in Figs. 5 and (i, consists of friction-plates I, carried in a recess in one face of the wheel, and a rod J, which connects a pin I2 on the friction-plate with the pusher. The other means (shown in Figs. 8 and 9) consists of a pin I2 on the wheel, which engages spring tappet-arms L L', pivoted on the connectingrod J and engaging stops m m. The stops fm m prevent the upper ends of the tappet arms or levers L L from being separated more than is shown in the drawings; but they may be pushed inward or toward each other. The pin 12in its revolution will not be resisted by that one of the arms L or L which it strikes upon the outer side, but will be resisted by the other and will therefore carry said arm and the link J along with it until the pin I2 slips off of its end.

In Fig. l2 a friction-plate I3, having a conical bearing on`the wheel B, is employed. This plate is held up to the wheel by a spring t, lying between the washer T and a thrustcollar V. In Fig. 13 a flat friction-plate I4 is shown, which is engaged by washer T', carried by key U, which extends through a slot in the shaft and is acted upon by a spring t', lying in a hole in the center of the shaft. This spring is backed by a bolt V screwing in the bore of the shaft. These various devices are designed to furnish a constant friction which is strong enough to actuate the pusher in either direction, but will yield when the pusher has been shifted from one eXtreme position to the other. The oscillation of the friction-plate or its equivalent is limited to an amount which will shift the pusher something less than the diameter of the circle of movement of the pin I2. The guides for the pusher form stops limiting its movement in either direction. The pusher, therefore, will not be moved except when the travel of the carriage is reversed.

The construction shown in Figs. 10 and ll differs from that just described in employing the cross-head E as the pusher and connecting the rod J to the horn. The connection of the rod J with the wheel B is also transferred to the upper side of the wheel instead of the lower side, as shown in Figs. 2 and 6. This last is done only to get the proper relative motion of horn and pusher upon the reversal of the carriage. The action of this form is in all respects similar to that of the form shown in Figs. l and 2. Itis somewhat preferred because it enables the length of the carriage to be kept somewhat less than with the other form.

In Fig. ll I have shown a rod w, which limits the movement of rod J in one direction. In the other direction its motion is limited by engaging the hub of the wheel B or a member of the friction device.

By the above or equivalent means the relative position of the horn and pusher is changed suddenly a limited amount by the reversal in movement of the carriage in addition to the gradual changein relative position caused by the progress of the carriage.

I have shown the two horns at opposite ends of the carriage as being provided with duplicate mechanisms of the kind just described. It is, however, evident that both horns and pushers may be connected and the same mechanism be used to operate both. It is immaterial as affecting the principle of my invention which of the constructions shown be used, as each is but a reversal of the other.

The central feature of my invention consists of the gradual and continued changing of the relative position of horn and pusher by the travel of the carriage and the sudden and limited changing of their relative positions at the time of reversing the direction of travel of the carriage. I do not, therefore, wish to be limited to the construction and method of operation herein shown, but to claim any form of construction which secures the gradual and sudden changes in relative position of horn and pusher such as above stated.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. The combination with a cableway-carriage and a horn thereon for the reception of fall-rope carriers, of means for shifting the horn by the reversal of the carriage.
